Packet tracer BGP configuration

mandla — Mon, 20 Dec 2021 14:24:40 GMT

@membersGood day. I am trying to configure eBGP between 2 routers, that are connected via a crossover cable. As per attachment, I keep getting stuck when trying to "update-source loopback100". Packet tracer finds fault after I type this command. What I am doing wrong?

Hello,

the correct configurations would be those below. Problem is: Packet Tracer does not support the commands highlighted, so you cannot peer with loopbacks...

router bgp 100
bgp log-neighbor-changes
no synchronization
neighbor 192.168.200.1 remote-as 200
neighbor 192.168.200.1 update-source Loopback 100
neighbor 192.168.200.1 ebgp-multihop 2
!
ip classless
ip route 192.168.200.0 255.255.255.0 192.168.10.2

R2

router bgp 200
bgp log-neighbor-changes
no synchronization
neighbor 192.168.100.1 remote-as 100
neighbor 192.168.100.1 update-source Loopback 200
neighbor 192.168.100.1 ebgp-multihop 2
